“There will never be another voice or spirit like Carlos. For 17 years the four of us have been on this incredible journey of Il Divo together, and we will miss our dear friend. We hope and pray that his beautiful soul will rest in peace,” the group added.

Aside from Marin, the pop-opera group is composed of David Miller, Sebastien Izambard and Urs Buhler.

Martin’s cause of death was not immediately clear from the post although last December 16, the group said they were “hoping and praying” for the singer’s speedy recovery.
